PSB48YSNBSS General Electric Refrigerator - Instructions

After replacing the Defrost Thermostat, Defrost Heater Assembly, and the Main Board, I concluded that the problem must be the Defrost Thermistor, which I replaced in less than 10 minutes and it fixed the problem! I cut the wires on the old thermistor and connected the new one after stripping the wires and taped the new connections with electrical wire. Fast and easy repair (the last part anyway ;).

Had to remove all the covers and fans to expose the condenser, which was difficult as the parts were frozen to it. The styrofoam covering the condenser made it almost impossible to defrost it. Therefore, I ripped the styrofoam off to expose the condenser. Was not really difficult to fix the styrofoam cover using metal tape. Replaced temperature sensor in aluminum block, and used butyl sealant to secure. Had to also re-install parts of ice-ball kit that were not well covered. Lots of parts to keep track of, but anyone could do it.

had to rewire the harness in place in freezer. should have removed door for more room to work . easy job if you have 4 foot arms and a 1 foot chest.

Very limited working space in this model. Must remove grill and disconnect elect connector on motor. One additiional tool suggested: Extendable rod with magnet on end because you will most likely drop something. First, remove two screws holding motor to metal strap. Tool must be inserted between blades of fan in order to get to the screws and this is the hard part. Fan and motor are removed as one assy and this takes some manuvering. Might have to remove front screw on metal strap to gain more room. I did not attempt to remove fan shroud. My fan was attached to the motor shaft with a metal clip. Spray a good lubricant such as PB Blaster on the shaft, wait a few minutes and press it or tap it out gently. Save misc parts on old motor for reassembly. Your set up may be different so check out everything before starting.
